Robust-GAP: Achieving Zero-Hallucination Causal Summarization in Hierarchical RAG

Gists Abstract This article introduces Robust-GAP , a hierarchical Retrieval-Augmented Generation (RAG) framework designed to eliminate semantic hallucinations and knowledge drift during multi-document log summarization. By combining dynamic causal graph extraction (DLCE), active topology verification (SGAV), and metadata provenance propagation (PAPP), the framework enforces strict citation…
